Siloxanes are a group of chemicals that are derived from silicone are typically used in cosmetics and hair products to soften the skin, smooth out imperfections and moisturize an otherwise dry canvas. Found in many makeup, skincare and haircare products. Ingredients to look for: cyclotetrasiloxane, cyclopentasiloxane, cyclohexasiloxane, and cyclomethicone.
While this ingredient has been described as having highly moisturizing properties, studies show the opposite. They show that propylene glycol partially dissolves the intercelluar cement of the stratum corneum , resulting in completely drying out the skin, making it more vulnerable to damage. Because propylene glycol is also used to enhance ingredient penetration, it can allow harmful ingredients to be absorbed more readily. This potentially increases the likelihood of allergic reactions and skin irritation. Ingredients to look for: Propylene glycol, butylene glycol, polyethelene glycol
5. FRAGRANCE / PARFUM
A term that is allowed to be used to disguise sometimes hundreds of constituents that make up a particular fragrance, none of which is required by law to be listed. Found in almost every homecare, laundry, bodycare, cosmetic, perfume, and bath product.
Many of the ingredients used to maintain the scent and color of perfume, lip balm and nail polish include phthalates, which have been banned in the EU and in children’s toys in California (phthalates are also used to plasticize products). Phthalates have been linked to reproductive disorders in both males and females, endocrine disruption, allergies and breast cancer, and a study conducted by Columbia University’s Mailman School of Public Health showed that children subject to high levels of phthalates in utero were 70 percent more likely to develop asthma between the ages of 5 and 12.
